/*
  This subHGraph constructor is for use with BoxPlacer.  It creates 
  a HGraph from:
   ->vector<CapoBlock*> 	all CapoBlocks
   ->HGraphFixed		hgraphOfNetlist

 The hgraph is a copy of the netlist hgraph, with the addition of:
  4*#CapoBlocks nodes
  4*#cells in all CapoBlocks edges.

  for each CapoBlock there are 4 new nodes, and an edge from each cell in
  the block to each of those nodes.
